Some very exciting news came from the Royal Family last night - The Duke and Duchess of Cambridge are expecting a third baby!
Kensington Palace shared the news on their official Twitter account saying: "Their Royal Highnesses the Duke and Duchess of Cambridge are very pleased to announce that the Duchess of Cambridge is expecting their third child.
The news caused so much excitement all over the world but there were a few people who said they saw the news coming a couple of months before.
You might remember in late July when Kate and William visited Poland that Kate made a joke about having more babies.
When Kate and William were on their royal tour of Poland and Germany, The Duchess was given some toys for a newborn baby and Kate made the joke:
We will just have to have more babies then.
This started a couple of rumours in the media but at this stage nothing was confirmed.
